if The invention relates to a radio receiving set, and moreparticularly to a stat on lndlcator or dial construction for radio receiving sets.

The primary object of the invention is the provision of a construction of this character wherein a spherical dial is supported to afford a logging chart of maximum areaand in which is arranged the radio receiving equip ment, the dial being exteriorly mapped or decorated, in this instance, indicative of the hemispheres of the world and readily selectively operated for bringing in broadcast ing stations working on varying wave lengths or meters.

Another object of the invention is the provision of;a construction ofthis character, wherein'the make-up thereof is novel in form and is attractive and unique in character.

A further object of the invention is the provision of a construction of this character which is extremely simple, thoroughly re.- liable and eliicient in operation, compact. neat in appearance and inexpensive to manufacture. f

With these and other objects in view, the invention consists in the features of construction, combina-tion'and arrangement of parts, as will be hereinafter more fully described in detail, illustrated in the accompanying drawings which disclose the preferred embodiment of the invention,and pointed out in the claims hereunto appended.

In the accompanying drawings Figure 1 is an elevation of a radio receivingset constructed in accordance with the in vention. I

sec- Y orly thereof and stationarily mounted a parti'tion or shield 24 which divides the said body Similar reference charactersindicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail,.the

radio receiving set comprises a stand A which preferably includes a base 10 ofcircular con tour supported upon feet 11 which are continuations of columns or posts 12supporting a circular guard orrail 13 elevated the re-. quired height from the base 10 of the stand. At a suitable point centrally of the base 10 is arranged a loud speaker 14 of. any approved type and upon the top of this speaker 14: is suitably fixed a bearing 15 having detachably mounted therein a forwardly in- 5 clined tubular axle 16, to the upper end of which is fixed a suitable mounting 17 fora radio receiving, mechanism 18 of. any approved or standard construction. v

Enclosing thereceiving set 18 and within the guard rail 13 of the stand is a spherical hollow body 19 of the required size, preferably. made in separable half sectionsand made from opaque material having the outer Onthe axle16is journaled a gear 21, the latter supporting the body 19 and this gear is included or in meshwith a train of planetary operating gears 22, one of which being oper-I atively connected to the condensers of the receiving set 18, so that on the turning of the body 19, the condensers of the receiving set 18 will'be simultaneously adjusted. It is, of course, understood that the speaker 14 is in electrical connection with the receiving set 18 and has its connections 23 trained upwardly' through the hollow axle 16 to said set, as shown in FigureQ ofthe drawings. 1 p

The spherical body 19 hasarranged interiinto two chambers or cells 25 and 26 respectively, while arranged between thesections of 9 said body and encircling the latter forexposure externally thereof is a scale band 27 having degree marks 28 on its outer face indicative of the meters of wave lengths, the band being made from translucent material. Mounted on the partition 24 and disposed surface thereof decorated; or mapped, in this V instance indicative of the world, as at 20,

close to the band 27 to co-extend with substantially one-half of its circumference is a light obliterating shield, guard or mask 29, for a purpose presently described.

- ner as presently described.

' said lamps or bulbs are projected toward the from Figure 2 of the drawings.

' broadcasting stations for the operation'of the r The shield 29 extends rearwardly from the artition 24L, While mounted on and projected forwardly of said partition 24isa triangular shaped'shield or screen 30, the forward apex 31 of which coincides with the center of the frontal portion of the band 27 inclose relation thereto to effect a shadow casting medium to function as a pointer or indicator co-acting with-the scale 28 on said band, in a man- Suitably arranged on the partition 24; contiguous to the outer faces of the sides of the triangular shaped shield 30 are electric bulbs 32, these being arranged in a suitable electric circuit in the equipment of the radio receiving set 18, and by reason ofthe forwardly converging sides of the shield 30, the light rays from band 27 so that the tip or apex 31 will break the light'rays and form a dark spot upon the band to have the said tip or apex 31 causea shadow at its locality directly upon the band which will be visibledistinctly through the same and thus serve as a pointer or indicator, the top and'bottom plates 33 and 34: on the shield 30 confining the beam of the light between said plates, as will be clearly obvious The body 19, concentrically of'the hub of the gear 21, is formed with an opening 35 to emit heat from the interior of said, body,

while diametrically opposite thisopeningin the body 19 is another screened opening 36 which permits the escapeof heat from within the'body, Also the body at suitable intervals throughout the extent of the sphere is perforated at 37 indicative of broadcasting stationsin determined areas of the map 20 on the outer face of saidbody. r i "Inithe' operation of the receiving set, to effect accurate tuning or the selection of set, the body 19 is manually manipulated so that a selected degree'in the scale 28 on the band '27 will be brought into register with the pointer constituted by the apex 31 of the shield 30 which pointer throws a shadow 'therefromontothe band by dividing the il-,

' lumination from the bulbs 32 .and in this mannerja predetermined broadcasting sta- 'tion will be tuned in, as on manual turning fof the, body,'the train of gears 22 simultaneously operating the condenser within the receiving set 18 which as previously stated can be of any standard equipment.

" Made. fast to-the top of the loudspeaker and encircling the spherical body 19 is the meridian ring 38'; ordinarily employed as a -part ofa revolving whirl globe.

' In the use of'the radio set, it will be apparent. that those portions of the band, the

band. r

opposite sides of that traversed by the pointer 31- will be illuminated for one-half of the circumference of the body, while the remaining portion of said band will be obscuredor unlighted and the pointer or indicator 31 through a shadow cast therefrom; Such shadow will be visible exteriorly of the body 19 upon the band for enabling accuracy of tuning in this radio set in selecting various located broadcasting stations.

The spacebetween theplates 33 and'3l confining the light from the bulbs 32 opens rearwardly of the body 19 and this light is obliterated from the band 27 confronted by the.

shield 29 and it will be obvious that the rear half of thebody beyond the area of the shield interiorly of-said body is lighted.
